随着生活水平的提高及食糖量的增加,龋卤发病率逐年上升。乳磨牙、恒磨牙的后牙牙面沟窝不平,有许多小沟裂,医生称之为窝沟,它是牙釉质发育结构上的缺陷,深浅不一,在咀嚼压力的作用下,窝沟内易藏一些食物残渣和细菌,刷牙、漱口难以清洁,常引起牙面龋齿的发生。若在牙齿萌出不久,牙齿未患龋齿以前,用一种高分子复合树脂材料封闭窝沟,就会有效的预防龋齿的发生,这种方法叫窝沟封闭。5-17岁是适合的年龄,对于龋齿易感的成年人也可窝沟封闭预防。窝沟封闭不磨牙、无痛苦,价格便宜,是目前全国指导组要求各地积极开展的一项防龋工作。
With the improvement of living standards and the increase of the amount of sugar, the incidence of dental caries increased year by year. Breast molars, permanent molars posterior teeth tooth surface uneven, there are many small cleft, the doctor called the fissure, it is structural defects in enamel development, varying shades, under the action of chewing pressure, fissure Easy to hide some food debris and bacteria, brush your teeth, mouthwash difficult to clean, often causing tooth decay. If the tooth eruption soon, before the tooth does not have dental caries, with a polymer composite resin sealing fissure, it will effectively prevent the occurrence of dental caries, this method is called fissure ditch closure. 5-17 years of age is a suitable age, for caries susceptible adults can also pit fissure prevention. Pit and fissure closed does not mourn, no pain, cheap, is currently the national guidance group requires around the active development of an anti-caries work.
